One Direction's Niall Horan has insisted there is no romance between him and Demi Lovato.
The Irish boyband star and the Disney actress - now appearing as a judge on X Factor USA - struck up a friendship, with even Simon Cowell jokingly warning Demi to "stay away" from Niall.
"Travelling around the world and all the promo that we do - it doesn't leave time for a girlfriend. It really doesn't. Demi is really cool and we're really good friends," he told the Daily Mirror.
Niall, who turned 19 this week, admitted that he's still pinching himself over his 'bromance' with Justin Bieber, who even sent him a birthday message. The duo hung out after the MTV Video Music Awards and later met up and had an impromptu jam session at Niall's home in London.
"Every day I wake up and think is this all a dream. It's just impossible to believe I've become good friends with some stars like Justin Bieber," he continued.
"I would call Justin a friend, someone I hang out with. It's really weird. I was on Skype to my friend the other night and Justin was with me. My friends were loving it."
